A force field confined to a collimated beam with clean borders is one of the principal characteristics of tractor and repulsor beams. Several theories that have predicted repulsive effects do not fall within the category of tractor and repulsor beams because of the absence of field collimation. For example, Robert L. Forward, Hughes Research Laboratories, Malibu, California, showed that general relativity theory allowed the generation of a very brief impulse of a gravity-like repulsive f… WebNov 27, 2024 · Tractor beams are familiar to many, thanks to the Star Wars, Star Trek and countless portrayals of UFO kidnappings.
